Three new high-state AM CVn binaries are discovered, giving a local space density of about 1 to 3 per 10^8 cubic parsecs and LISA detection estimates near 36% of the Galactic population.

abstract
High speed photometry of KUV 01584-0939 (alias Cet3) shows that is has a period of 620.26 s. Combined with its hydrogen-deficient spectrum, this implies that it is an AM CVn star. The optical modulation is probably a superhump, in which case the orbital period will be slightly shorter than what we have observed.

A survey of ultra-compact high-state AM CVn binaries with ZTF and Gaia: New discoveries and observational constraints on Galactic space density
Three new high-state AM CVn binaries are discovered, giving a local space density of about 1 to 3 per 10^8 cubic parsecs and LISA detection estimates near 36% of the Galactic population.
